Pencil sharpener



FIG. 1 is a perspective view of a pencil sharpener showing my new design;

FIG. 2 is a reduced scale right side elevational view, the left side being a mirror image thereof;

FIG. 3 is a front elevational view, the vertical cut-out surface on the opposite side being plain and unornamented; and

FIG. 4 is a top plan view, the bottom plan view being a mirror image thereof except that the larger circle is omitted and the blade end is exposed.

The characteristic feature of the design resides in the longitudinal grooves on the two opposite and identical sides. 

The ornamental design for a pencil sharpener, as shown and described.
